I doubt that anyone even remembers Site Server 3 - most of those that had any contact with it will have spent the last decade trying to forget. But, on the off-chance that someone out there does remember it, perhaps you also remember what can be done to un-blacklist a user who has been blacklisted as a result of supplying incorrect login details 3 times?

I have a user that's been blacklisted that I really really need to recover, and yet I can find no way to do this. (I'm not even able to figure out where the blacklist is stored - I'd be quite prepared to nuke it if that's what it takes).
